    Natural Gas

    1 Natural gas is produced from reservoirs deep beneath the earth's surface. It is a fossil fuel（矿物燃
    料）,meaning that it is derived from organic material buried in the earth millions of years ago.The main corn-
    ponent of natural gas is methane（甲烷）.
    2 The popularity and use of clean natural gas have increased dramatically over the past 50 years as
    pipeline infrastructure（基础设施）has been installed to deliver it conveniently and economically to millions
    of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50
    states in the U.S.,and is the leading energy choice for fueling American homes and industries.More than 65
    million American homes use natural gas.In fact,natural gas is the most economical source for home energy
    needs,costing one-third as much as electricity. In addition to heating homes,much of the gas used in the United
    States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to
    plastics for healthcare,computing and furnishings.Natural gas is also used in a significant number of new
    electricity-generating power plants.
    3 Natural gas is one of the safest and cleanest fuels available. It emits（发出）less pollution than other
    fossil fuels sources. When natural gas is burned,it produces mostly carbon dioxide（二氧化碳）and water va-
    por一the same substances emitted when humans breathe.Compared with some other fossil fuels,natural gas
    emits the least amount of carbon dioxide into the air when combusted（燃烧）一making natural gas the clea--
    nest burning fossil fuel of all.
    4 The United States consumes about one-third of the world's natural gas output,making it the largest
    gas-consuming region in the world.The U.S.Department of Energy Information Administration forecasts that
    natural gas demand will grow by more than 50 percent by 2025.
    5 There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natural
    gas can be found in Russia , West and North Africa and the Middle East. LNG（液化天然气）has been pro-
    duced domestically and imported in the United States for more than four decades.Today,the leading import-
    ers of LNG are Japan,Korea,France and Spain.

    Home Heating

    Central heating became popular only after the Civil War.Typically,coal-burning
    furnaces（火炉）fueled the early systems.Natural gas had developed into the leading fuel
    by 1960.Its acceptance resulted in part from its wide uses.Because it comes primarily
    from U.S.and Canadian fields , natural gas is also less vulnerable（脆弱的）than oil is to
    war.Oil remains the most important fuel in a few areas,such as New England.
    Electric heating dominates most areas with mild winters and cheap electricity,including
    the South and the Northwest.It was made popular at least in the South by the low cost of
    adding electric heating to new houses built with air-conditioning.Bottled gas,which is
    somewhat more expensive than utility gas,is the fuel of choice in rural areas not served by
    utility pipelines.Wood is the leading heating fuel in just a few rural counties.
    Home heating,which accounts for less than 7 per cent of all energy consumed in the
    U.S.,has had a commendable（值得赞扬的）efficiency record : from 1 978 to 1 997 , the
    amount of fuel consumed for this purpose declined 44 per cent despite a 33 per cent
    increase in the number of housing units and an increase in house size.The
    U.S.Department of Energy,however,forecasts that energy used in home heating will rise
    by 14 per cent over the next two decades.That rise is small considering an expected 21 per
    cent increase in the number of houses and the trend toward larger houses.
    Natural gas and electricity will probably dominate the home heating market for the next
    two decades.Solar（太阳的）heating never became popular because of cost and limited
    winter sunlight in most areas;in 2000 only 47,000 homes relied on it.

    Practice 3　　Energy-saving vehicles were part of the Green Transportation Festival in the US in 2003. The vehicles shown were designed to reduce America’s dependence on oil and help the environment.　　There are exhibits of cars and buses at the festivals. Most of them use little gas or use another kind of fuel such as natural gas. People are also urged to consider simpler ways of getting around, such as walking, biking and using public transportation systems.　　The United States has less than five per cent of the world’s population, but uses about twenty-five per cent of the world’s oil. More than half of the nation’s oil is imported. Most of it goes to transportation.　　Festival organizers said progress in technology was making it possible for Americans to reduce their dependence on oil. That is because the kinds of energy-saving vehicles are increasing. Efforts to reduce oil imports in the United States would also have important environmental benefits. The burning of oil as fuel is responsible for gases blamed for climate change. When gasoline is burned in cars, it also pollutes the air. This leads to many health problems.

    正确答案： 【参考译文】
    2003年在美国举行的“绿色交通节”上展出了节能车,这类车辆的设计目的是减少美国对石油的依赖及改善环境。
    交通节期间展出了轿车和公交车,它们大多使用少量汽油或其他燃料一如天然气。展会同时呼吁人们考虑更为简单的出行方式,如步行、骑自行车或使用公共交通系统。
    美国人12不足世界总人口的5%,却使用了约25%的世界石油产量,其中一半以上是进口的;大部分进口石油用于交通运输。
    交通节的组织者说,科技的进步可以使美国人减少对石油的依赖,因为这类节能型汽车的产量在不断增加。减少石油进口对美国将会产生重要的环保效益。燃油产生了导致气候变暖的温室气体,饱受指责。燃烧的汽油还会污染空气,这导致了很多健康问题。

    from U.S.and Canadian fields , natural gas is also less vulnerable（脆弱的）than oil is to
    war.Oil remains the most important fuel in a few areas,such as New England.
    Electric heating dominates most areas with mild winters and cheap electricity,including
    the South and the Northwest.It was made popular at least in the South by the low cost of
    adding electric heating to new houses built with air-conditioning.Bottled gas,which is
    somewhat more expensive than utility gas,is the fuel of choice in rural areas not served by
    utility pipelines.Wood is the leading heating fuel in just a few rural counties.
    Home heating,which accounts for less than 7 per cent of all energy consumed in the
    U.S.,has had a commendable（值得赞扬的）efficiency record : from 1 978 to 1 997 , the
    amount of fuel consumed for this purpose declined 44 per cent despite a 33 per cent
    increase in the number of housing units and an increase in house size.The
    U.S.Department of Energy,however,forecasts that energy used in home heating will rise
    by 14 per cent over the next two decades.That rise is small considering an expected 21 per
    cent increase in the number of houses and the trend toward larger houses.
    Natural gas and electricity will probably dominate the home heating market for the next
    two decades.Solar（太阳的）heating never became popular because of cost and limited
    winter sunlight in most areas;in 2000 only 47,000 homes relied on it.
